[Q] Issue with batter life, root or not?

Hi
I have an i9505 for a month and it's great.
the problem is if no wifi, Bluetooth, gps and ... ON, I have around 15% battery drain from 12:00 am to 7:00 am.
I had an Htc before and it was dual core 1.5 Ghz and it's at night battery drain was around 3%.

the only thing which is annoying is this. I already turned off most of the Samsung programs but no difference.
I don't know what to do? If I root my device and use a custom ROM would be any difference?

Look at the links in my signature about insanely better battery life when idle. Consider those options to assist you. Make sure you read the first post of the thread thoroughly because there are some tradeoffs.
